To all whom 'it may concern.'V 1

Be it known that I, GUs'rAvE-LANGE, a citizen of the United States, residing ,at'Chicago,y 111 the county ofCook-andState QofIllinois, have invented certain newyand 'useful `Iinprovements in Ash-Sifters, of which Vthe following is a specification. i

The object of this inventionis to provide an ash sifter which shall be thoroughly dust proof and at the same time easy of manipula- A further object of the invention is to so constructthe parts that a pan ofashescan be inserted within the sifter l without disturbance of theashes andwithout the necessity for reaching the arm of theoperator into they sifter in :positioning the pan, thereby; permitfrom start to 'linishwithout danger of vsoiling the clothes andwithoiit inconvenience in depositing the ashes inpositionj- The invention' consists 'n the construction and combination-'of parts hereinafter described and'claime'd.

. In the drawings, Figure 1 isa sectional' elevation of the outer box, showingthe sifting` mechanism in elevation, Fig.12"fa sectional elevation taken at right angles to Fig. 1 Fig.

3 a sectional plan view of'theouterbox, showl ing the inner mechanism in! elevation; and Fig. 4 a detail, p artly'in section, showing thev formation of the shaft upon whichthe, cage is mounted.

' The sifter, as a whole, comprisesy an outer box 5, of rectangular formation, comprisinga front wall 6, arear wall 7, sidewalls 8, a floor 9, and a roof or top 10;` The vfront-wallhas located therein upper andlower hingeddoors 11 and 12, respectivelyl* In alinement with the upper dooris a cage 13, comprising a solid floor 214, adapted to receive and supportan ash pan 15, which floor.has`secured thereto;

three arched bars 16, which are connected yat their ends with the edges-ofthe floorfand are reinforced by longitudinally extending bars 17, giving to the whole structure a cage-like formation. Thecage is provided, at its rear` end, with a solid end wall 18and, at its front the forwardarch bar l'provides an` open end to permit the pass-ageof the pan therethrough. 1

The cage, as a whole, islmounted'upon a xed shaft 20, which V `extends from rear to front of the box, therear end being entered through the rear wall and into an outer plate 21, whichholds the shaft l rigidly position featuresV of i `Aspin:atifmliimi,Noymbef 25, 1907. 'seriai No. coach.v

best shown in Fig. 4. The sleeve is provided,

at-itsY outer end', with a handle 24; and the V`ca,g ;e 1isslidable'upon the' fixed 'shaft and is positioned thereon by a strap 25, which emraces the shaft, the movement of the cage beinglimiteolV by a stop collar 26 secured to the shaft a slight distance forward of the strap 25'.. The cageis normally held in upright positionfby means ofV a pair of forwardlyfprojecting brackets 27 and 23 secured tothe rear wall 7 near the outer edges thereof andimmediatelybelow the lioor of the cage. VThe bracket 28 projects inwardly to a greater degree than the bracket 27, and the cage is mounted. upon the fixed shaft slightly off center, as shownirr Fig. 2, with the result that, when the-cage is pulled forward to its limit, the heavier side, which normally rests upon and is supportedby the short bracket 27, will "be released, causing the cage to swing down by gravity into the position indicated in Vdotted lines in Fig. 2, the reverse movement or swing of the cage being limited bythe longer bracket 23 against which the cage willstrike when thrown into reversed position. i Immediately below the cage is a rocking sifter 29, com rising semi-circular end walls 130 anda ha -cylindrical screen body 31, which -is connected, at its edges, to longitudinallyextendin rails 32, and, at its center,

Y edto be `actuated by a forwardly extending handle 35, `which-is rigidly connected with -theiforwardend of the rocking sifter., The

sifteris adapted to be jolted by contact with I at-the rearend.y The front end of the shaft l a stop-36, which serves to limit the swing of the sifter in one direction, thereby more thoroughlyv agitatinP the ashes contained in thesifter than would bethe case if the latter were allowedto swing free.

I mediately below the rocking sifter is a chute'37, adapted to discharge into an ash 'receivin pan 38, which rests upon the floor of ythesifter'and is adapted to be removed through the lowerV door 12. Immediately abovethe space occupied by the ash receiving pan is a pair of supporting rails 39, which extend from front to rear of the sifter box and support a pan or receptacle for the coal from which the ashes have been sifted.

In use the upper door Will first be opened and a pan containing unsifted ashes will be shoved into position on the flat floor of the cage, which, when in normal position, Will be on a level with the upper` door, so that there will be no necessity for the operator reaching his arm into the interior of the sifter box nor disturbing the ashes in any way prior to the closing of the box. After the pan of ashes has been thus positioned, the upper handle 24 will be pulled forward, which movement releases the heavier side of the cage from its support and allows the cage containing the pan of ashes to overturn by gravity until its movement is stopped by the contact of the cage With the longer bracket 28. This movement dumps the ashes through the open portion of the cage and deposits them in the rocking sifter. The rocking sifter is then swung back and forth, by the action of the handle 35, which brings the sifter, with every oscillation, into contact with the stop 36, thereby thoroughly agitating the ashes and coal, causing the former to sift out through the screening and fall through the chute and into the pan 38 provided therefor. After the ashes have thus been completely sifted, an em ty pan for the reception of the coalcan be s oved in along the guide rails 39 and immediately above the pan containing the sifted ashes, after which the coals can be removed from the rocking sifter by overturning the latter until the farther edge of the sifter is swung around into contact With the stop 36, which of course will causethe coals to roll out of the sifter and fall through the chute into the pan provided for their reception. I

It will be seen from the foregoing description that the various operations can be performed without any necessity for reaching into the interior of the sifter box and without the possibility of being soiled by dust or dirt generated during the sifting operation. The method of depositing the ashes in the sifter by overturning the cage is one which permits the operation to be performed by a slight pull on the handle, the cage being thereafter overturned by its own weight, and depositing the ashes in position after the box has been thoroughly closed and the dust prevented from escaping.

What I regard as new and desire to secure by Letters Patent is:

1. In an ash sifter, the combination of a sifter box, a screen sifter within the box, a rotatably mounted cage above the screen sifter and adapted to receive and hold a pan of unsifted ashes, a support for normally holding the cage in upright position, and a handle adapted to move the cage away from the support and permit its reversal, substantially as described.

2. In an ash sifter, the combination of a sifter box, a screen sifter within the box, a revoluble cage eccentrically mounted above the screen sifter and adapted, when in normal position, to receive and hold a pan of unsifted ashes, a sup )ort for the heavier side of the cage, and a iandle adapted to move the cage away from the support to permit it to reverse itself by gravity and discharge the ashes into the sifter, substantially as doscribed.

3. In an ash sifter, the combination of a sifter box, a screen sifter located within the box, a revoluble cage eccentrically mounted above the sifter and comprising a flat floor adapted t0 receive a pan of unsiftcd ashes, and an openwork top adapted to embrace and hold the pan of unsifted ashes supported upon the floor, a bracket at the rear side of the sifter box for supporting the heavier side of the cage, and a handle adapted to pull the cage forward and away from the supporting bracket for permitting its reversal, substantially as described.

4. In an ash sifter, the combination of a sifter box, a screen sifter located within the box, a revoluble cage eccentrically mounted above the sifter and comprising a vflat floor adapted to receive a pan of unsifted ashes, and an openwork top adapted to embrace and hold the pan of unsiftcd ashes supported upon the floor, a bracket at the rear side ol' the sifter box for supporting the heavier side of the cage, a handle adapted to pull the cage forward and away from the supporting bracket for permitting its reversal, a receptacle below the screen sifter adapted to receive the ashes, and guideways above said receptacle adapted to receive and su )port a suitable receptacle for receiving coals after sifting, substantially as described.

5. In an ash sifter, the combination of a sifter box provided with upper and lower doors, a cage in alinement with the upper door. and adapted to receive and hold a pan of unsifted ashes, means for reversing the cage to discharge the ashes from the pan, a rocking screen sifter pivoted below the cage,

a stop for limiting the movement of the rocke ing screen sifter, a chute below the rocking screen sifter, and a receptacle, in alinement with the lower door, for receiving sifted ashes from the chute, substantially as described.
